I got mine at Michael's but you can also get some at any hand craft place : JoAnn's, Hobby Lobby, or Art of Texas here in Houston... Assembly is pretty easy. I did not want to bother with the eyelet setter and hammer so I got the automatic eyelet setter and it worked great. It took me about 30 seconds per booklet ! (once perforated, and for this I just used my desktop 2-holes perforator).
